- Those sixty niche Adsense sites that you own, did you personally hand-made each one of them, or did you buy them pre-made and preloaded with PLR (or may be not) articles? If it's the latter, then chances are they won't do too well.
- Yes those really high paying keywords are BS indeed, and most are way too competitive for you to succeed with to begin with. For instance the infamous "mesothelioma" got a lot of attention due to its generally high price; yet less and less people are getting successful with it. Keywords that are $5 to $7 are okay though. On top of everything, it's the keyword research that matters. I prefer Wordtracker.com
- I checked out NicheGeek.com (nice looking and professional by the way!) A little tip, to blend your ads even more, change the link colour of the left sidebar hyperlinks to the same colour of the Adsense links.
